In /config/recaptcha.php, enter your reCAPTCHA public and private keys.

If you are not using the most recent version of reCAPTCHA, set version to 1.

If you are upgrading to v2 of reCAPTCHA, note that your keys from the previous version will not work, and you need to generate a new set in the reCAPTCHA admin.

The package ships with a default validation message, but if you want to customize it, add the following line into resources/lang/[lang]/validation.php:

'recaptcha'=>'The :attribute field is not correct.',

Usage

v2 (No Captcha)

In your form, use {!! Recaptcha::render() !!} to echo out the markup.

In your validation rules, add the following:

$rules= [// ...'g-recaptcha-response'=>'required|recaptcha', ];

v1 (Legacy)

In your form, use {!! Recaptcha::render() !!} to echo out the markup.

In your validation rules, add the following:

$rules= [// ...'recaptcha_response_field'=>'required|recaptcha', ];

It's also recommended to add required when validating.

Customization

reCAPTCHA v2 allows for customization of the widget through a number of options, listed at the official documentation. You can configure the output of the captcha through six allowed keys: theme, type, lang, callback, tabindex and expired-callback.

In the config file, you can create an options array to set the default behavior. For example:

// ...'options'=> ['lang'=>'ja', ],

would default the language in all the reCAPTCHAs to Japanese. If you want to further customize, you can pass options through the render option:

echoRecaptcha::render([ 'lang'=>'fr' ]);

Options passed into Recaptcha::render will always supercede the configuration.

Language

To change the language of the captcha, simply pass in a language as part of the options:

Limitation

Because of Google's way of displaying the reCAPTCHA, this package won't work if you load your form from an AJAX call.
If you need to do it, you should use one of the alternate methods provided by Google.
